I usually just ask someone in the pub who has either had the work done or knows someone else who has. It's usually better to get someone in who you know has done a decent job.
Otherwise, a local Facebook group or Nextdoor should yield decent results.
Oh crumbs, I wasn't suggesting that. Just that you are better off asking around and finding someone who is recommended rather than just picking a random person.
Ah right. Either way, beware people! I've made this mistake and it somewhat ruined a friendship. I didn't even do the cutting off. The guy sort of bodged a job and then ran off on shame
